VBRICK-MOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 275,715, dated April10, 1883.

i Application sied January 10,1582. (Nomea-.1.)

To all whom it may concern Be it known that I, CARL FRIEDRICHSOHLIGKEYSEN, of Berlin, in the Kingdom of Prussia and German Empire,have invented an Improvement in Brick-Molding Machines, of which thefollowing is a specification.

My invention refers to an improved brickmolding machine in which thepressing-cover is lifted or shifted from the press-box by means of adirect movement of the hand; and it is based upon the application of thesaid direct movement of the hand in lifting the said pressing-cover anddropping` the same in proper time.

My invention is illustrated in the accompanyin g drawings, showing theseveral modili cations of my said machine, like letters indieating thesame or identical parts of the same. I have chosen the said letters ofreference in such a manner as to have each main part of machineindicated by a separate letter, while the under parts belonging to thesaid main parts are indicated by the same letter and continuous numbersattached to the latter.

Figure lis a side view, showing one modification of my im proved machinein vertical section. Fig. 2 is an end view, showing the same intransverse section; and Fig. 3 is a top. view of the same modification.`

A is a table-plate on the standards A', being connected by thecross-piece A2, said tableplate having an inclined arm bifurcated at itsupper end and carrying the shaft B. Upon the latter is fastened astar-piece, B, with striking-lever B4, weighted lever B3,andpushing-lever B2.

The brick-mold C is screwed upon the fore part of A, said mold having amovable bottom, C5, and a cover, C', fastened to the striking-lever B4.The small shaft C2 is .journaled in bearings on the cover-plate Csaidshaft being provided with two catches, O4, the fore one of which havinga lever, C3, extending in an upward direction. Said catches O4 catchunder another pair of catches formed ou the mold C for the purpose offastening the cover upon the mold while the brick is being pressed.

O6 are two hanging arms connected with each other and carrying the saidmovable bottom C5. They are provided with the roller C".

vD is a double rail moving between the fixed rollers A3, and having asmall catch-lever, D, pivoted to its end, which can turn in a backwarddirection only. The fore part of the rail D is provided with theinclined loop D2, pivoted at its lower fore end, and being madeadjustable at its upper end in an upward and downward direction. Theroller G'I runs in the said loop D2. The bent lever D4, with weight D5,is pivoted at'A5 to the cross-piece A2, and its upper end is heldbetween the pins D9 D1U and the double rail D, so that it is bound tomove with the latter.

Eis a shaft journaled underneath the tableplate A, having between thearms U6 a cam, E', and a lever, E2, the latter being connected to thelever E4, pivoted at E5 by means of the connecting-piece E3.

- The operation of the machine is as follows: By raising thestriking-lever B4 the pushinglever B2 strikes against the catch-lever Dand moves it forward. 'At the saine time the loop D2-lifts the rollerC?, and thereby the moldbottom C5 is raised above the upper edge of themold C. The brick molded in O is consequently brought to the outside,and can be taken O', whereupon the pushing-lever is pushed entirely overthe lever D. rlhe weight D5, having been raised by the forward movementof D, drops down again and presses the rail D back again -by means ofthe pins D10 and D9. The same effect on the rail D might be produced bythe weight D5 being connected to the latter by means of a rope andpulley. In consequence of the backward movement of D the roller O runsdown again until the bottom C5 rests on table A, as before. Loam is-then inserted in the mold C and beaten down by the striking-lever B4and cover C', whereupon the latter is fastened to the mold by means ofthe catches G4. Hereupon the lever E4 is pressed down, which causes thebrick in the mold now to receive a pressure from below after it has beenbeaten down from above. Finally the cover is unloosened, and lever B4 israised again to bring bottom C', with the molded brick, to the outside,as above described.

It' one blow by the lever B4 and cover C should prove to beinsufficient, and several strokes must be made, then the catch-lever Dmust be brought out of action, so that in raising the striking-lever thepushing-lever will not move IOC forward the rail D. For this purpose adrawing-rod, R. is pivoted to the table-plate A, as shown in Fig. 4 ofthe drawings, the lower end of said drawing-rod being held in aperpendicular position by the weight R2, and being connected by means ofa light chain, B', to the lower end ofthe catch-leverD. rIhe drawing-rodis also provided with a light rod, B3, extending with its handle throughan aperture in the frontispicce of the table-plate A, and having acatch, lt. By drawing the rod R3 to the outside until B* catches behindthe lower edge ofthe said aperture the catch-le ver D assumes aninclined position, so that the moving pushing-lever B2 cannot touch it.The entire apparatus and thelever D', by means of the drawing-power ot'the weight R2, will at once assume their normal position again as soonas the catch It is set free.`

The said Fig. 4 shows another modified con struction of my improvedmachine. rlhe loop orincline D2 has been substituted by a rack, D, andpinion D?. Iart ofthe said pinion I)T is made with a. smooth rim, D8,and acts like a cam carrying the roller C7, with bottom C5. By raisingthe striking-lever B4 the rack DU is pushed forward and rotates the saidpinion D7, the smooth part DB of the latter thereby lifting the rollerC7 until the mold-bottom, with the brick, lies free above the mold G.Now, when raising the lever Bt is continued, the le- D will swing free,and rail D will be pushed back again by the weight D5 coming down.

The pushing-lever may in some instances be dispensed with, and themovement ot' raising the said striking-lever by means of leverpressuremay be applied in a direct manner for lifting the mold-bottom anddropping the same; but these are mere mechanical modifi cations andcombinations of parts known. I therefore shall but refer to two of suchmoditications.

In the modification shown in Fig.5 the hanging arm U6 is connectedrigidly to an arm, G8, extending from the table behind the mold andterminating in a catch, B2. The catchlever D' is fastened to thestriking-lever B4, and in raising the latter the said lever D carriesthe catch B2 and the mold-bottom C5 above the edge of' the mold. Thenthe brick has been taken off, thelever B4 is raised a little, whereuponthe catch B2 slides off the lever D', and then drops down. Now the moldis refilled and the striking-lever B is brought down, the catch-lever D'turning on its pivot, as hereinbefore described, as soon as it touchesthe said catch B2.

In the modification shown in Figli the hanging arm H is made movable,thesame, near its lower end, being guided between two rollers, A3, andhaving above the latter the catch B2, rigidly connected to it. Thecatch-lever D is applied to the hanging arm C, while the manipulationand operation are the same as described with reference to Fig. 5.

In the modification shown in Fig. 7 a second lever, K, is applied to thestandard A', said lever K being connected to the strikinglever B4 bymeans ot' a drawing-rod, I'I. The catch-lever D is arranged and operatesthe same as in the modification shownin Fig. 6.

In any of the instances referred to it is not material for thecatch-lever to drop back again into itsnormal position by means of itsgravity. Such movement may also be provided t'or by a spring combinedwith the said lever in any suitable manner. Neither will it be necessarythat the said movement be a turning movement,asinscmeinstances a slidingmovement, as indicated in Fig. 12, may be applied with advantage.

Figs. 8, 9, 10, and 1l illustrate the construction and combination ofthe lockingeatches with the two faces of the mold. The said catchesconsist each of a thin plate, M, fitting in a tapering slot cut in thesaid faces, and are tightly held in position by means of pivots N,extending from each face through each plate, and holding the latter inits place by means of a splint. The said plates M are provided withstrong rims made of steel, the horizontal parts of which also serve forholding the toggie G4 ofthe cover during the pressing. Binding a thinplate like M by means of lockingcatches may also be effected, as shownin Fig. 11. In this instance the saidplateon its upper outside carriesthe locking-catch o, and on its inside it has several cross-pieces, p,the upper rim of which has an ascending form, and tits dovetail-like ina corresponding slot cut into the outer face ot' the mold. By means ot'a small wedge, q, the whole plate is then keyed in an upward direction,so as to be prevented from talling out. The said plate may be stiffenedin any convenient manner, whileitis obvious that the cross-piecesp maybe arranged different from- Fig. ll. Ihe said cover-plate may enter themold from about one-fourth to.

three-fourths inch, so as to compress the ma terial in the latterjustsufficiently to prevent its escaping from the mold.

In the modification shown in Figs. 12, 13, 14,15,16,and 17 the mold islaid open by means of shoving or pushing off the coverplate, instead ofraising the same, as in the modification hereinbefore described. W'iththis modification the pushing movement is utilized in the same manner asthe said lifting movement-thatis to say, the movable bottom is broughtout of the mold while the latter is open, and is dropped again in propertime for refilling. With this modified form of my improved machine,beating down the brick is dispensed with, while the mode ofpressingisthe same as hereinbefore described. 'Ihe tableplate A is provided withtwo grooves for sliding the frame F in a forward and backward direction.The said frame F is connected with two standards, F', whereinisjournaled a cam-shaft, F3, carrying the cam F4. Between the saidstandards the ram or stamper C slides up and down, inclosing at the sametime the ICO lIO

said cam F4 on both its upper and lower side, the said stamper G', bythese means, being bound to follow any movement of the said cam F4. Tothe said table is iXed the arm A", having a collar for the short spindleF, the latter ou one side, being provided with an open slot,

F5, while on the other sidelit carries a ilywheel or pressing-lever. Asquare-edged pivot on the cam shaft F3 tits in the said open slot F5.The armi) is fastened to the crosslpiece on the back side of the frameF, said arm extendingfrom under the table A, and is provided with aprojection. An inclined bar, D', is pivoted to one side of the saidproject-ion, and with its lower end rests upon the arm D, the latter, bymeans of two rollers applied thereto, being carried by the frame-pieceA2. To the mold-bottom G5 is suspended the arm G6, having a roller, G7,the latter being suspended within a short distance from above the arm D.The said roller is touched by the inclined bar D', being pushed or movedunderneath the same, so that in pushing backward the frame F with arm Dthe saidiuclined barD' will raise the mold-bottom U5 until the latter israised above the upper rim ofthe mold O. The brick formed is then takenoff the said bottom C5, and the frame F pushed backward a littlefarther, so that the roller C', with hanging arm G6 and bottom C5 willdrop down again, and

,fresh material may be inserted into the said mold C. The frame F isthen pulled-forward again, the said roller C7 passing by the projectionD2 and raising. the inclined bar D', resting loosely upon the arm D andbeing pivoted to the said projection, as hereinbefore described. Inpulling forward the frame F the edge of thev cover-plate C', slidingclosely across the mold C, will take away all the loam 4c jutting out ofthe latter. Then the cover-plate C' has assumed its normal positionabove the mold G it is pressed down by means of turning the cam-shaftF3. The latteris then turned back again and the frame Fpushed backward,as before described. The said cam-shaft may be turned by means ot' alever or ily-wheel, either directly connected therewith or connectedwith its short slotted spindlel F6, journaled in the arm A6. It isobvious that the said cam-shaft F3 may also be applied to the frameA2 ofthe table, and may be provided with one cam each outside of the saidframe, as illustrated in Fig. 16 of the drawings. The cam F4 isconnected with the pressing-cover by means of two .drawing-rods, F', theupper ends of which are bent rectangular, the pressing cover being keptcontinually in a raised position by means of springs or weights, andbeing provided with a cross-piece, F3, projecting laterally from itssides, said projections catching under the rectangular endsv of thedrawingrods F7 in pushing forward the frame F. The operation of qthemodification is obvious and need not further be described. With thismodification, also, the raising of the molded brick may be effected bymeans of a combinahaving pivoted thereto the elbow-lever G G',

the lower part, G', of which is connected to the hanging arm C6 by meansof the connecting-rod H. To the other or fore end of the bent arm D isvsuspended a catch-lever, D', which, in pushing backward the frame F,with the said arm D fixed to the same, strikes against the lever-,armGr, and carries the same along until, by means of lever-arm G',connecting-rod H, and hanging arm C6, the pressing or mold bottom hasbeen raised out of the mold. Then the operation is interrupted for amoment, and the molded brick is taken olf the said bottom, whereuponframe F and arm l) are pushed backward a little farther, so that thelever-arm G will slide ofi' the catchlever D', in consequence whereofthe parts G' H GG and the mold bottom connected therewith will drop downagain. The mold is then refilled, and frame F, with arm D, is pulledforward again, the catch-lever D', pivoted to the arm D, sliding acrossthe leverarm G.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-
